Graeme's Free Games presently features some highly accessible versions of Namco's all-time classic Pac-Man. All feature the option to reduce the number of ghosts as well as giving the facility to adjust the speed of the ghosts and your Pac-Man independently.

There's a really well thought out one-switch version that features the best solution I've seen yet to navigating a maze at speed. A mouse compatible version offers a way to play for head-tracker, eye-tracker and other users too. This too offers a really well thought out solution.

"October 20, 2008 - Koonsolo announces that Mystic Mine can be played with a single button. People and children with limited mobility will have no trouble with the controls. The difficulty also adapts to the current player, making sure that everyone can enjoy and finish the gameat their own skill level, regardless of age, experience and disability."
